" The upstairs is almost always hotter than the downstairs during the
summer. Noticeably hotter. If we get the upstairs comfortable, the
downstairs is like an ice box.
Any suggestions? The house is about 20 years old. Also, I'm trying
to avoid tearing up the roof.


*This topic has been mentioned here a few times. More insulation, an attic
exhaust fan, reconfiguring your ducts, adjusting your vents, or adding
another zone could all help to one degree (No pun intended) or another.
